My iphoto will not open it just sits there and acts like it is about to load by bouncing on the dock. I get no message saying it can't open it will eventually just stop acting like it's going to load. Now the main photo icon for iphoto has eve changed it looks like a blank piece of paper with a pencil and pen at the bottom of it, and it used to be that signature iphoto sunset. Please help I don't want to lose all my photos!
